Hey, judging by the diary, the indicators are pretty good. What are the reasons for the fluctuations, and what is their range? The plant looks healthy. During the seedling stage, a daytime temperature of 22-28 is normal, and with high humidity and good airflow, it's fine up to 30 degrees. At night, it's better not to drop below 20, as the roots are very sensitive and can die. I'm managing by setting a timer on the oil heater at night. Humidity can be kept within 30-70%, with LED lights there are usually no issues with humidity. If it's high, you can put boxes with salt or silica gel in the box. If it's low, a humidifier. It's all simple. The most important thing: don't overlove the plant, everything should be in moderation, just like with kids. π Good luck!
